Abstract
Abstract A grid structure is provided defining rows and columns of square openings therein which when connected to a circuit board provides a guide means for positively indexing coaxial wire terminals with contact pins extending from terminals on the circuit board. The grid structure also serves as a common grounding means for the shield conductor of each of the coaxial wires.

Claims Analysis
Total Claims: 9
Claim 1
Independent Claim
174 words
A coaxial wire connector guide and shield grounding structure comprising: a conductive grid wall structure defining small apertures therein securely mounted to a unit which has a plurality of contact means extending therefrom; each of said apertures surrounding a different one of said contact means but spaced therefrom so that there is no electrical interconnection therebetween; coaxial wire terminators each having a signal wire contact means for connection to a respective one of said contact means extending from said unit and each having a shield contact means electrically connected to the shield conductor of said coaxial wire and surrounding said signal wire contact means and electrically insulated therefrom; each coaxial wire terminator being slightly smaller in width than said apertures so as to be guided therein to positively mate with said contact means; and a grounded grid wall contact means on at least one of said grid walls adapted to complete an electrical circuit through said shield contact means when said coaxial wire terminator is inserted within said aperture in said grid wall structure.
Claim 2
Dependent Claim
174 words
A coaxial wire connector guide and shield grounding structure comprising: a conductive grid wall structure defining small apertures therein securely mounted to a unit which has a plurality of contact means extending therefrom; each of said apertures surrounding a different one of said contact means but spaced therefrom so that there is no electrical interconnection therebetween; coaxial wire terminators each having a signal wire contact means for connection to a respective one of said contact means extending from said unit and each having a shield contact means electrically connected to the shield conductor of said coaxial wire and surrounding said signal wire contact means and electrically insulated therefrom; each coaxial wire terminator being slightly smaller in width than said apertures so as to be guided therein to positively mate with said contact means; and a grounded grid wall contact means on at least one of said grid walls adapted to complete an electrical circuit through said shield contact means when said coaxial wire terminator is inserted within said aperture in said grid wall structure.
Claim 3
Dependent Claim
114 words
Apparatus according to claim 1, wherein said grid structure is made of strips of material having slits extending halfway through a width thereof, said slits being spaced from one another at a distance defining an aperture width; a cutout portion of the same width as said slit located below said slit in the other half of the width of said strips; and a pair of opposing retaining lobes extending into each of said slits, whereby said strips may be interconnected by inverting one with respect to another and interconnecting via said slits, the lobes being dimensioned and located along the length of said slits to fit into said cutout portions of the interconnected strip.
Claim 4
Dependent Claim
55 words
Apparatus according to claim 2, wherein both surfaces of the strips are alternately gold plated and tin-lead plated in stripes extending from the top to bottom thereof across the width along the entire lengths, each tin-lead stripe including one of said slits and cutout portions, the gold stripes forming said grounded grid wall contact means.
Claim 5
Dependent Claim
46 words
Apparatus according to claim 3, wherein the joints between said interconnected strips are soldered by causing the tin-lead plated stripes to rise above their melting temperature whereby they form a solder joint between the contiguous edges of the interconnected slits, cutout portions and the retaining lobes.
Claim 6
Dependent Claim
67 words
Apparatus according to claim 3, wherein said grounded grid wall contact means includes a finger cut from the strip in the area of each of said gold plated stripes except for one end so that they can be bent into said apertures to form a good pressure contact between said shield contact means of each coaxial wire terminator inserted in said apertures and the grounded grid wall.
Claim 7
Dependent Claim
56 words
Apparatus according to claim 3, wherein said shield contact means of said coaxial wire terminator includes at least one outwardly spring biased portion for contacting a gold plated stripe of a wall of the aperture to form a good pressure contact electrical connection between the shield conductor of said coaxial wire and the grounded grid wall.
Claim 8
Dependent Claim
43 words
Apparatus according to claim 1, wherein said electrical unit is a circuit board and said contact means are male contact terminals extending vertically from said board and arranged in a predetermined pattern to be compatible with the aperture locations in said grid structure.
Claim 9
Dependent Claim
79 words
Apparatus according to claim 1, wherein said coaxial wire terminator comprises a receptacle attached at one end to the center conductor of said coaxial wire and adapted to receive a male contact; insulation means surrounding said receptacle; said shield contact means comprising a shieLd potential sleeve surrounding said insulator and being connected to the shield conductor of said coaxial wire; and said sleeve being shaped the same as said apertures and being of a size to fit snugly therein.
